Formation of an Hfr cell Chromosome -F plasmid The F plasmid sometimes integrates into the bacterial chromosome by homologous recombination, generating an Hfr cell; the process F pilus F* cell Integrated is reversible. F plasmid Hfr cell Formation of an F' cell - Integrated F plasmid - Chromosome An incorrect excision of the Hfr cell integrated F plasmid brings along a portion of the F plasmid chromosome, generating an F' cell. Chromosomal DNA- F pilus F' cell FIGURE 8.23 Formation of Hfr and F' Cells An Hfr cell is created when the plasmid integrates into the chromosome as a result of homologous recombination. Note that the process is reversible. An F' cell is created when certain recombination events result in an incorrect excision that removes a piece of the chromosome along with the F plasmid. This process is also reversible.

Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
